How to Swap Two Numbers in Python?

Hi Dev,

This post is focused on How to Swap Two Numbers in Python. I explained simply about Swapping of Two Numbers in Python. it's simple example of Python program to swap two numbers without using third variable. In this article, we will implement a Python Program To Swap Two Numbers. you will do the following things for Write a Program to Swap two Numbers Using Python.

Python program to swap two numbers; Through this tutorial, you will learn how to swap two numbers with and without third variable in python.

so let's see following examples with output:

Example 1: Python program to swap two numbers using the temporary /third variable

# Python program to swap two variables using temp variable
 
num1 = input('Enter First Number: ')
num2 = input('Enter Second Number: ')
 
print("Value of num1 before swapping: ", num1)
print("Value of num2 before swapping: ", num2)
 
# swapping two numbers using temporary variable
temp = num1
num1 = num2
num2 = temp
 
print("Value of num1 after swapping: ", num1)
print("Value of num2 after swapping: ", num2)

Output:

Enter First Number: 5
Enter Second Number: 6
Value of num1 before swapping:  5
Value of num2 before swapping:  6
Value of num1 after swapping:  6
Value of num2 after swapping:  5

Example 2: Python program to swap two numbers without using the temporary /third variable

# Python program to swap two variables without using third varible
 
num1 = input('Enter First Number: ')
num2 = input('Enter Second Number: ')
 
print("Value of num1 before swapping: ", num1)
print("Value of num2 before swapping: ", num2)
 
# swapping two numbers without using temporary variable
num1, num2 = num2, num1
 
print("Value of num1 after swapping: ", num1)
print("Value of num2 after swapping: ", num2)

Output:

Enter First Number:  9
Enter Second Number:  8
Value of num1 before swapping:  9
Value of num2 before swapping:  8
Value of num1 after swapping:  8
Value of num2 after swapping:  9 

I hope it can help you...
